Birder / Enjoyer of all Nature
I was just birding yesterday in central Montana and found a dozen or more peeps on the edge of a small pond (I already ID'd the larger Bairds Sandpiper). I think they are Leasts because of their more brown plumage and having a little longer decurved bill compared to the Semi. You can find more photos here https://ebird.org/checklist/S117004960
